Remotes

Certain models require the transponder on the key to be changed to work with the immobiliser system in the car. These chips are programmed using different methods based on the model of Lexus. This is done using a special device which sends a code chip to unlock the doors or to start the engine.
Certain Lexus cars are constructed with a single piece of hardware which includes the key head and remote. These are easier to replace since no separate chip is required. This kind of key could also be a bit less expensive.
All fobs eventually lose battery power, regardless of the type of key. This can be a frustrating experience, but it is possible to get your Lexus back up and running with a little know-how.

Transponder Chips
Transponder chips are found in the key heads of a majority of new vehicles manufactured after 1995. They can be used to disable immobiliser systems. The head of a key which contains a transponder chip is able to be removed to reveal a steel L-shaped key. Having a replacement key or fob with a transponder chip is a multi-stage process that includes precise cutting of the replacement keys and programming the transponder chip to link up with the vehicle's immobiliser.
A transponder is a device with Non-Volatile Memory. It is comprised of a set of windings that are fine wires coiled around a tube. They look like those in an electric motor. The windings generate a coded message that the car is able to read. If the code is correct the car will begin to move.
There are two types of transponder chips. The one is known as the 80-bit and the other is known as the circle + (General Motors). The former type is reusable but needs to be unlocked by a machine that is specially designed to function in a different compatible vehicle. The latter is a bit more difficult because the previous ones are often broken and drilled or thrown away when key cases are replaced. However they can be used with a key-service that does not require a battery.
Immobiliser Systems
Immobiliser systems are electronic security measures that stop thieves from starting your vehicle. It works by sending a signal from your vehicle to the key when you attempt to start it. The chip inside the key responds by sending a unique code that must match that of the vehicle in order for it to start. If the codes don't coincide, your engine will stop immediately to prevent theft.
Modern smart keys and fobs are equipped with an embedded transponder that can store electronic security information in a format that is not easily copied. When the key or fob are inserted into the ignition, they send this code to the ECU. The ECU examines the code against the one that is stored in its memory and activates the fuel system and the ignition circuit if they match. If the codes do not match, your engine won't be able to start - even if an armed robber attempts to short-circuit the ignition circuit.
The replacement of a key or fob involves an entire process that involves cutting the new blade precisely and programming it so that it syncs with your car's system. There are a variety of immobilisers used in different years and models, and each requires its own distinct programming process. We utilize Ross-Tech software to ensure that your replacement key is programmed correctly to ensure the best performance and security.
